Abstract
A shaft torque measuring device in the form of a compact sleeve may be slid on the steering shaft of an automobile and requires only about the same axial space as the diameter of the shaft itself. Two collars are integrally interconnected by four cross members, some of which carry strain gauges. Frictional force maintains the collars in place with torque applied to the steering shaft thus causing the cross member to bend. This deformation is sensed by the strain gauge bridge to produce a torque measurement.
