<p>The drive coupling comprises first and second components, one of which carries pins (17) off-set from, but parallel to, the axis of rotation of the coupling. The pins carry weights (18) which are coupled to the other component by further pins (19) carrying abutments (20) engaged in slots (21) in the weights. The weights are biassed against outward movement by leaf springs (22) which are located against curved outer surfaces of the weights. The end of the springs engage an annular part which is a skirt portion of the other component and the springs have ears (24) intermediate their ends which locate in slots (25) formed in the side faces of the weights.</p> |
