Mechanical device used to connect or disconnect driven shaft from driving shaft while power transmission from driving to driven shaft is called as clutch.

Positive and friction clutch are different types of clutches.

Friction clutch is further divided into :

1) Plate clutch
2) Cone clutch
3) Centrifugal clutch

Square shaped jaws are driven in both directions.

Spiral shaped jaws transmit power in one direction
