ABSTRACT:
A torque wrench has a non-jarring design such that it resets without jarring the output shaft after it delivers the preset maximum torque, it accommodates interchangeable output shafts so that a variety of different drive tips may be employed with the same handle, and it has a variable limiting torque value because it can accommodate interchangeable output shafts having uniquely designed cam surfaces.
