Abstract

A torque device for guiding a first torque device member relative to a second torque device member includes the first and second torque device members. Each of the torque device members has an operational axis of rotation and three clamp bodies spaced about the operational axis. The clamp bodies are movable between a retracted passive position and an extended active position. The torque device also includes a guide ring on one of the torque device members. The guide ring includes one or more guide ring sections. In addition, the torque device includes at least two guide elements on the other of the torque device members. Each guide element being movable with one of the clamp bodies of the respective torque device member. When the clamp bodies of the respective torque device member are in their retracted positions, the guide elements abut or are close to the guide ring, and when the clamp bodies of the respective torque device member are in their extended positions, the guide elements are moved away from the guide ring.
