``Smart'' Attachment for Utility Damage Prevention

A torque transmission device for telescoping drive or propeller shafts. The device comprises a slide relatively slidably mounted within a torque transmission tube and a resilient bellows connected between the slide and a sleeve fixed to an end of the torque transmission tube such that the bellows is in sliding contact with the slide and/or the tube for its stabilization. A first slide ring is mounted on the sleeve for sliding contact with the slide. A second slide ring is also mounted on the sleeve in sliding contact with the slide or at the end of the slide in sliding contact with the interior wall of the torque transmission tube in which case the bellows is enclosed entirely within the tube between the latter and the slide.
