Abstract: A torque limited applicator is useful for a wide variety of purposes where a mechanical device, such as a fastener, is to be driven but a maximum level of torque not exceeded. The applicator is reusable, and preferably easily constructed from integral pieces of plastic. A torque applying element with internal cam followers and a fastener drive structure with a drive element and a cam element may either be removably positioned with respect to each other, or a retaining ring and deformable pin may attach them together. A plug may be provided to reduce the possibility of tampering, provide a tamper evident seal, and to prevent foreign material from entering the area of cooperation between the cam element and cam followers, as well as providing an area for indicia indicating the maximum level of preset torque. Color coding for different torque levels for the applicators may be provided.
