You can make an adapter to use with a torque wrench. Just take an open ended tubing wrench and heat it until it starts to glow about a half inch from the head and bend each end so they are 90? and the two ends are in center alignment and parallel with each other when looking down the length of the wrench. Get an allen head socket for the end where you will place the torque wrench. I have used this technique a couple of times, quenching the bends with a water mist from a spray bottle after bending keeps the metal from getting too soft or too brittle. A wrench made like this will not be off much when you torque an object, of course, you cannot apply a lot of torque without twisting the wrench handle. I prefer Williams or Craftsman wrenches for this mod.
