Coupling is a device used to join two shafts say the driver and the driven to transmit power functions of shaft coupling.

• To provide connection and disconnection between the driver and follower.

• To provide Alignment facilities.

• To allow flexibility between shafts.

• To reduce transmission of shock loads.

• To introduce protection against overloads.

• To alter vibration characteristics of rotating units.

Requirements of good shaft couplings:

1. It should be easy to connect and disconnect.
2. Should be able to transmit full power.
3. Should hold shaft in alignment.
4. Should be able to reduce the shock.
5. Should have no projecting parts.
6. Should have smooth surfaces.
