Low coupling
There are many like flexible coupling, jaw coupling, sleeve coupling, tire coupling, pin and bush coupling, rigid coupling, etc

The design of a system affects its coupling efficiency, which refers to how closely components are connected. A well-designed system with low coupling has minimal interdependence between components, leading to better efficiency. Conversely, a poorly designed system with high coupling can result in inefficiencies and difficulties in making changes.
There should be low dependence and high interaction between the modules. The dependence should be low so that the module can work in absence of another module. So, there should be low coupling ad high cohesion in software design.
There are many sources for you to buy interior design concepts. You can check out blogs, which usually have great information from others who are in your shoes. Here is another source: interiordesignconcept.com/
They are of similar design, but a fluid coupling simply transmits torque (with some frictional loss), while a torque converter amplifies torque, similar to a reduction gear.
A coupling circuit connects the output of one stage of a system to the input of another stage. There are many different types of coupling circuits (e.g. direct coupled, resistor coupled, capacitor coupled, transformer coupled) each with its own advantages and disadvantages.

On the website Hugh Graham Creative there are lots of useful information about design concepts for free. The article is also enriched by an informative chart and useful examples.
