Device, system and method for testing screwing devices

A test device (10) for testing screwing devices, comprising an outer body (13) in which a shaft (14) is rotatably supported with an end (15) for connection to a screwing device and an opposite end (16) for connection to a joint to be screwed, the device (10) further comprising a first transducer (18) for detecting the rotation angle of the shaft (14) and a second transducer (19) for detecting the torque transmitted by the shaft (14) between the two ends (15, 16), characterized by comprising internally a control unit (20), an NFC communication module (31) that is suitable for receiving an identification code from the outside, a memory (30), and communication means (24, 31) for communicating with the outside, the first and second transducers (18, 19), the NFC communication module (31), the memory (30) and the communication means (24, 31) being connected to the control unit (20) so that the control unit stores in the memory (30) an identification code received from the NFC communication module (31) associating it in the memory (30) with test data obtained from the first and second transducers (18, 19) and, via the communication means (24, 31), sends to the outside data obtained from the contents of the memory (30).
