<p>A coupling of the "Tracta" joint type comprises a driving member rotatable about a first axis, a driven member rotatable about a second axis, and two intermediate members for operatively coupling the driving member to the driven member. The improvement comprises elastomeric bearing means disposed between and engaging each set of mutually opposing bearing surfaces of the driving, driven and intermediate members under compression when torque is applied to the driving member about the first axis.</p> |
