Abstract: The invention relates to a torque tool, a torque testing device or a rotational angle testing device, with a user identification unit for identifying the user of the tool. The system further includes a user data unit in which user-specific data for handling the tool are collected, a work data unit in which work data for applications of the tool are collected, a learning unit connected to the user data unit, and the work data unit, in which data are recorded during an operation of the tool by the user and are compared with the data collected in the user data unit and the work data unit and are adapted in the event of a deviation. An adaptation unit is connected to the user data unit and the work data unit, and the operation of the tool is adaptable and controllable, depending on the user-specific data and the work data.

Abstract: The disclosure relates to a communication device (36, 72, 74, 78) for an operating tool (10, 68, 70) and/or for a measuring device to transmit data between the operating tool (10, 68, 70) and the measuring device and a data processing system (62, 66). The communication device (36, 72, 74, 78) comprises an authentication module (42) for authentication of the operating tool (10, 68, 70) and/or of the measuring device when transmitting data. A transmission module (38) transfers the data over a mobile network (40) via Internet connections. The invention further relates to an operating tool (10, 68, 70) and/or measuring device with means (76) for generating user data and/or usage data with a communication device (36, 72, 74, 78) for exchanging data between the operating tool and/or measuring device and a data processing system (62, 66).
