Abstract
The torque and angular displacement transducers in a yield threshold controlled wrench apparatus are relocated to reduce the problems encountered therewith from the harsh physical environment experienced by such transducers in conventional designs. In one preferred embodiment, both the torque and angular displacement transducers are located at completely remote locations from the movable elements of the wrench mechanism and are each housed in a conventional hydraulic fitting to be more readily replaceable for maintenance purposes, as compared to the transducers of conventional designs.
