Abstract: A torque measuring device, in particular for use by means of commercially available tools, includes a measuring head with a connecting element provided for torque transmission. To permit the torque measuring instrument to be used universally, the connecting element is embedded in the measuring head and connected at one end to the component to be tightened and at the other end directly to a torque-producing tool. As a result, the torque measuring device can be used both with commercially available wrenches or other tools operated by electric motor or pneumatically. The torque measuring device is placed directly on the components to be tightened, while the tool is inserted into an existing tool holder. A particular advantage is that the torque measuring device is constructed so as to co-rotate, and therefore the possible use of driven tools is provided, on account of the possible rotation.
