A load detection device for monitoring the engagement force between a tool and a workpiece, comprises means having a free end for transmitting a force, the force being transmitted at the free end. A load cell has one face juxtaposed that free end of the means for transmitting a force, for monitoring the force of that force-transmitting means. Biasing means is mounted between the free end and that one face of the load cell, the biasing means providing a biasing force to urge the load cell monitoring the force away from that free end. A piston rod adapter is provided, having a blind bore at one end and an open end opposite that one end; the opposite end being slidably mounted to the free end of the means for transmitting a force. The biasing means and the load cell are mounted in the blind bore of the piston rod adapter, and are interposed between the free end and the bottom of the blind bore. Means for limiting the movement of the means for transmitting a force relative to the piston rod adapter are included; the limiting means being mounted to the means for transmitting a force such that the force transmitted at the free end of the means for transmitting a force is counteracted by the biasing means, and the net effect of the force is monitored by the load cell to determine the engagement force between the tool and the workpiece.
