A coupling device plays a role in connecting two rotating shafts, which then transmit torque motion. Coupling is also used as a power transmission on the engine.
Coupling is designed with a very simple way of working, namely the end of the shaft is connected to the coupling, so that the shaft moves or rotates, but the shaft shafts cause a loud jerk, so generally in the coupling mounted dampers known as rubber couplings or coupling couplings.
