The standard length of rigid metal conduit (RMC) is typically 10 feet. When including one coupling, the effective length might be slightly less depending on the type and design of the coupling used. However, for practical purposes in installation, the 10-foot length is commonly utilized. Always check local codes and manufacturer specifications for any variations.

With the possible exception of a variable reluctance transformer, you should always avoid core saturation of any type of transformer. When saturated the magnetic characteristics of the core material is radically changed and the coupling coefficients will be very different. Additionally, many transformers can overheat and be damaged.
Membrane-type flexible coupling is used in steam turbines.
Lovejoy is the legacy company/brand behind the original straight jaw flexible coupling. A Lovejoy flexible jaw coupling is comprised of two hubs and an elastomeric spider that accommodates minor misalignment and avoid metal to metal torque transmission between the hubs. One main advantage is that it can still work during slightly failed condition. If the spider fails or wears away, the jaws of the two hubs will generally engage with each other and continue carrying torque for some period of time. This type of coupling is generally resistant to dirt, moisture, sand and grease. These couplings come with a wide selection of hub and spider materials to handle a wide array of operating temperatures and torque transmission requirements.
In software engineering, the preferred type of coupling is "loose coupling." Loose coupling allows components or modules to interact with one another with minimal dependencies, making the system more flexible and easier to maintain. It enhances reusability and facilitates changes, as modifications in one module are less likely to impact others. This approach contributes to better scalability and easier testing of individual components.

A claw coupling is a type of mechanical coupling used to connect two shafts, allowing for the transmission of torque while accommodating misalignment and vibration. It typically consists of two claw-shaped components that interlock, providing a secure connection. Claw couplings are commonly used in various applications, including pumps and motors, due to their ease of installation and ability to handle moderate loads. They also allow for quick disconnection when maintenance is needed.

It is a fluid coupling using a viscous (thicker type) fluid, similar to the coupling between the drive and driven impeller of an automatic transmission in a car.
To extend rigid conduit, you can use a coupling specifically designed for rigid conduit, such as a threaded or non-threaded coupling. Additionally, you can opt for a conduit connector or an appropriate fitting that matches the conduit size and type. It's important to ensure that all connections are secure and meet local electrical codes for safety and compliance.
Without knowing more about your specific shotgun,. type of sight and what is the misalignment, we are going to have to say take it to a gunsmith. There is not much information in your question.
External coupling occurs when a component communicates or collaborates with infrastructure components (e.g., operation system functions, database capability, telecommunication functions). Although this type of coupling is necessary, it should be limited to a small number of components or classes within a system. Software must communicate internally and externally. Therefore, coupling is a fact of life. However, the designer should work to reduce coupling whenever possible and understand the ramifications of high coupling when it cannot be avoided.
