Shaft couplings are used to couple or attach two shafts together, typically in an assembly where one shaft rotates and drives the other shaft -- for example, if a motor were to drive a pump, there would be a coupling between the two shafts.
Shaft couplings can be rigid (accommodating no misalignment) or flexible (accommodating some angular and/or radial misalignment of the two shafts). More information on various types of couplings is available here:

knuckle threads are used in railway carriage couplings.
A monoblock pump is a small pump that has no base plates, couplings, or guards, which keeps it small. A centrifugal pump is larger, with added features and impellers to give the pump hydraulic lift.
There are wood pipes, glass pipes, and even marble pipes.
Most commonly used is argon, but Helium can be used as well.
Drill mud is used.
knuckle threads are used in railway carriage couplings.
Rotary couplings is a mechanism used to move fluid that is under pressure from a static inlet to a rotating inlet. They can be bought at sites like DSTI and Amazon.
A coupling is a device used to connect two shafts together at their ends for the purpose of transmitting power. Couplings do not normally allow disconnection of shafts during operation.
Unfortunately, the answer to that question is difficult to come by without knowing the location and use of the rotary couplings. The answer could be anywhere from $200-$2000. Please specify use for rotary couplings.
Pipe
A coupling is a device used to connect two shafts together at their ends for the purpose of transmitting power. Couplings do not normally allow disconnection of shafts during operation, however there are torque limiting couplings which can slip or disconnect when some torque limit is exceeded.The primary purpose of couplings is to join two pieces of rotating equipment while permitting some degree of misalignment or end movement or both. By careful selection, installation and maintenance of couplings, substantial savings can be made in reduced maintenance costs and downtime.

A coupling is a gadget used to associate two shafts together at their closures to transmit control. Couplings don't ordinarily permit separation of shafts amid task, however there are torque restricting couplings which can slip or detach when some torque confine is surpassed.
To protected pipe thread. Do not use as a pipe coupling. Thread don't taper and the wall is to thin and could crack.
