Toy building block

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. The first engagement formation threadingly joins the interconnector to the first connecting part. The second engagement formation can resist rotational movement of the interconnector relative to the second connecting part but allows movement of the interconnector in the axial direction of the shafts. When a torque transmitted by the shafts exceeds a predetermined value, the interconnector rotates relative to the first connecting part at the threaded engagement formation. The resistance to rotational movement relative to the second connecting part causes the interconnector to move in an axial direction of the shafts, and come out of engagement with the first and/or the second connecting part.
