Abstract: Described herein is a torque-limiting coupling provided for connecting coaxial, first and second rotating shafts. The coupling includes a first connecting part on an end of the first shaft and a second connecting part on an end of the second shaft. An interconnector joins to the first connecting part at a first engagement formation, and joins to the second connecting part at a second engagement formation.
