Coupling

A coupling is a device used to connect two shafts together at their ends for the purpose of transmitting power. The primary purpose of couplings is to join two pieces of rotating equipment while permi
An improvised flexible coupling made of car tyre pieces connects the drive shafts of an engine and a water pump. This one is used to cancel out misalignment and dampen vibrations.

Increasing number of coils allows for greater angular misalignment.
Constant-velocity joint
Videos
A constant-velocity joint is a mechanical connection between two rotating shafts, that keeps them rotating at the same speed, while allowing the shafts to be at an angle to each other as they rotate.
Coupling
…operations. This type of coupling is mostly used to couple electric motors and machines. There are various types of constant-velocity (CV) couplings: Rzeppa joint, Double cardan joint, and Thompson coupling. In this coupling, the muff or sleeve is made into two halves parts of the cast iron and they are joined…
