A clutch assembly includes axially aligned shafts, one driving and one driven, the driving shaft including a plurality of slots and the other a plurality of apertures aligned with the slots. Elongated roller bearings are positioned in the slots and apertures to lock the shafts together, a resilient member being used to urge the bearings radially inwardly. In the event that one of the shafts slows substantially relative to the other, the bearings move radially outwardly to declutch the shafts.
