Abstract
The invention relates to a clutch assembly (8) for providing selective engagement with a rotatable shaft, in particular for selecting between manual and powered driving of an output drive such as a door, shutter or gate. The clutch assembly (8) comprises a stop (16) arranged to rotate with the shaft (18), a cam (20) arranged to move relative to the shaft (18), and a follower (24) arranged to rotate around the shaft (18) and axially movable along the shaft in and out of engagement with the stop (16). The follower (24) is operatively associated with the cam (20) so that movement of the follower relative to the cam brings the follower into engagement with the stop (16) by axial movement, so causing rotation of the shaft (18).
