Torque wrench assembly

A torque wrench assembly comprising:

• a coupling arrangement;
• a torque generating device that is coupleable to the coupling arrangement;
• wherein the coupling arrangement comprises:
• a housing;
• a transfer shaft, at least a portion of which is positioned in the housing,
• a first drive shaft having an end extending from the housing;
• a second drive shaft having an end extending from the housing;
• first drive gear means, coupled to the first drive shaft, for providing rotation of the transfer shaft;
• at least second drive gear means, slidably coupled to the transfer shaft, for providing rotation of the second 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 means along the transfer shaft;
• and wherein the coupling of the first drive gear means and the at least second drive gear means via the transfer shaft provides that the first and second drive shafts are able to provide an at least essentially equal torque.

A coupling arrangement for use with a torque generating device in a torque wrench assembly, the coupling arrangement comprising:

• a housing;
• a transfer shaft, at least a portion of which is 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;
• 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 are able to provide an at least essentially equal torque.
