Abstract: The invention relates to a multi-bolt or nut torque wrench device (10, 10a, 10b) for installing or removing a plurality of threaded bolt or nut members (150). The device includes a reaction plate (20), a plurality of torque stations (30) mechanically coupled to the reaction plate (20) and configured for receiving one of the bolt or nut members (150) in operational use. In operational use, each torque station (30) applies reaction force directly and only to the reaction plate (20), and in that the reaction plate (20) and plurality of torque stations (30) are configured to be located substantially at an upper side of a respective flange (110) of a part to be coupled or decoupled from a part (100) in operational use, such that the torque wrench device (10, 10a, 10b) is configured for resting substantially on the plurality of threaded bolt or nut members (150) in operational use.
