Abstract
An apparatus displays the torque reached by a tightening tool on a case which is independent from the tool proper. For this purpose, the tool has diodes for transmitting infrared radiation, for example, while the case has diodes for receiving this radiation. In this way, the tool may be employed in any position while the case is placed in a visible region and displays the value of the torque applied to the part to be tightened.
