KEY CLUTCH

A clutch is a mechanical device that engages and disengages power transmission. In the simplest application, clutches connect and disconnect two rotating shafts (drive shafts or line shafts). The clutch connects the two shafts so they may be locked together and spin at the same speed (engaged), locked together but spinning at different speeds (slipping), or unlocked and spinning at different speeds (disengaged).

A key is a small, shaped metal implement for operating a switch in the form of a lock. A key may similarly be a pin, bolt, or wedge inserted between other pieces, or fitting into a hole or space designed for it, so as to lock parts together. It may have incisions cut to fit the wards of a particular lock, which is inserted into a lock and turned to open or close it.
