The device (10) further comprises 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). The device (10) further comprises a control unit (20), an NFC communication module (31), a memory (30), and means (24, 31) for communication with the outside. The control unit stores in the memory (30) an identification code received from the NFC communication module (31) and associates it in the memory (30) with test data obtained from the first and second transducers (18, 19). Then the communication means (24, 31) send to the outside data obtained from the contents of the memory (30). A method for testing and managing the tests and a system which comprises in addition to the test device (10) also at least one NFC tag (33) are also described. ## Claims ### Claim 1 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). ### Claim 2 (depends on 1) The test device (10) according to claim 1, characterized in that it comprises an internal electric power supply battery (32). ### Claim 3 (depends on 2) The test device (10) according to claim 2, characterized in that it comprises a recharging circuit (38) for inductive charging of the internal electric battery (32). ### Claim 4 (depends on 1) The test device (10) according to claim 1, characterized in that it comprises a pushbutton (34) connected to the control unit (20) for controlling the reception and/or storage of an identification code and test data obtained from the first and second transducers (18, 19). ### Claim 5 (depends on 1) The test device (10) according to claim 1, characterized in that the communication means comprise a connector (24) and/or a wireless data transfer unit (31). ### Claim 6 (depends on 1) A test system comprising at least one test device (10) according to claim 1 and at least one NFC tag (33) for sending an identification code to the NFC communication module (31). ### Claim 7 (depends on 6) The test system according to claim 6, characterized by comprising a base (36) for receiving the device (10) and equipped with a wireless communication module (35) for exchanging data with said communication means which include a wireless data transfer unit (31). ### Claim 8 (depends on 6) The test system according to claim 6, characterized by comprising a base (36) for receiving the device (10) and equipped with a transmitter module (37) for transferring electrical power by means of inductive coupling so as to transfer electric power to the test device (10) in order to recharge its internal power supply battery (32). ### Claim 9 (depends on 6) The test system according to claim 6, characterized by comprising an external analysis unit (21) which receives test data from the test device (10). ### Claim 10 (depends on 6) A method for the execution and management of tests of the operation of at least one screwing device on a joint in at least one assembly station, comprising the test system according to claim 6, comprising the steps of using the test device (10) for: a) receiving, via the NFC communication module (31), at least one identification code associated with the screwing device and/or the joint and/or the assembly station; b) storing the at least one identification code in the memory (30); c) acquiring angle and torque measurements from the first and second transducers during the action of the screwing device on the joint; d) storing data obtained from such measurements in the memory (30) and associating them with the at least one identification code; repeating steps a)-d) if necessary for other screwing devices or the same screwing device; and finally: e) transferring obtained data from the contents of the memory (30) to an external analysis unit (21). ### Claim 11 (depends on 10) The method according to claim 10, characterized in that, before executing steps a)-e), steps are taken to associate with the screwing device and/or with the joint and/or with the assembly station (33) an NFC tag which sends a corresponding identification code to the NFC communication module (31) when the test device (10) is moved to within a distance allowing communication between the NFC communication module (31) and the NFC tag (33).
