ABSTRACT:
Apparatus and methods for coupling a driving shaft and a mating tool shaft to transmit rotational forces and axial tension and compression forces between the shafts. The coupler provides for axial tension transmission through tension transmission surfaces spaced-apart from torque and compression transmission surfaces of the mating tool shaft. Reversible shaft locking means prevent accidental disconnection of the driving shaft and mating tool shaft. A separate safety lock release attachment is preferably removed during tool shaft rotation and can automatically hold the driving shaft stopped when used to release the shaft locking means for a tool change. Malfunction (e.g., improper seating) of the shaft locking means with the attachment ring in place results in a positive visual indication of the malfunction.
