Abstract: A torque-limiting driver with a drive element configured to have a rounded protruding feature that comprises an embodied roller which maintains contact with a cam element under a preload by a biasing member and contained within a handle housing. When a predetermined torque value is reached, which exceeds the preload by the biasing member, the drive element moves about the surface profile of the cam element and linearly within the handle housing, preventing torque above the predetermined torque value from being delivered to the shaft assembly from the handle housing.
