Abstract: A torque wrench assembly system comprising a housing, a transfer shaft positioned in the housing, a first drive gear arrangement coupled to the transfer shaft; at least a second drive gear arrangement slidably coupled to the transfer shaft; a first drive shaft coupled to the first drive gear arrangement and having an end extending from the housing; a second drive shaft coupled to the second drive gear arrangement and having an end extending from the housing; a torque generating device that is coupleable to the transfer shaft, to the first drive gear arrangement and/or the first drive shaft; wherein the distance between the first drive shaft and the second drive shaft is slidably adjustable by the slidability of the at least second drive gear arrangement along the transfer shaft; and wherein the coupling of the first drive gear arrangement and the at least second drive gear arrangement via the transfer shaft provides that the first and second drive shafts can provide an at least essentially equal torque.
