The invention relates to an interface device (100) for tensioning or relaxing a bolt (10) in a nut-and-bolt assembly (10,20), wherein the bolt (10) extends in an axial direction. The interface device (100) comprises a frame (150) having a first end portion (100-1) and a second end portion (100-2), opposite to the first end portion (100-1). The first end portion (100-1) of the frame (150) is provided with a rotatably-mounted nut ring (130) for receiving and rotating a conventional nut (20) provided on the bolt (10) in operational use of the interface device (100). The second end portion (100-2) of the frame (150) comprises a mechanical tensioner nut (190) being configured for reacting on the frame (150) and for receiving a part of the bolt (10) that extends beyond the conventional nut (20) in operational use of the interface device (100). The mechanical tensioner nut (190) is further configured for being driven by a low-pressure torque tension tool (200) to tension or relax the bolt (10) in operational use of the interface device (100). In this way the invention provides for a very compact torqueing solution for which low-pressure torqueing tools can be used. |
