Abstract

A coupling comprises an inner member (1) having an outer convex spherical periphery (S1) centred about a central point (C). The first inner member has a torsional axis (A1) extending through the central point. A second member outer ring (2) has an inner concave spherical periphery centred on the central point and complementary to the outer periphery of the inner member. One of the first inner member (1) and second member (2) has an elongate projection (M1) projecting parallel to a line extending radially of the central point into a corresponding elongate slot (K1) in the other. The slot and projection are elongate in a plane parallel the torsional axis (A1). The projection and slot act to transmit torque about the torsional axis (A1) from one to the other. The inner member and second member are rotatable one relative to the other about the said central point in a direction constrained by the projection and slot.
