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. 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.

Abstract: A sanitary clip-on handle arrangement that may be clipped onto a toilet seat when needed by a user. The clip-on handle includes a handle portion that is fixed to a clip portion. The clip portion provides a clamping arrangement that may be operated by a user to enable the clip-on handle to be temporarily clipped onto a hinge mounted toilet seat for use in lifting and lowering the toilet seat. The handle portion may be rotatably fixed to the clip portion to be movable between a first extended position enabling a person to easily grasp the handle portion and a second tucked position that is less obtrusive.
