According to

Torque Wrench Adapter Formulas

what you say is true provided the adjustable wrench is less than 2-inches long. I think they are saying that keeping under 2-inches makes the error small enough to ignore for their application.

When i tried it, I did see a difference compared to using a socket: 95 inch-pounds using just the socket versus 70 inch-pounds with my 6.3-inch long adjustable wrench set at 90° from the major axis of the torque wrench. This was the same reading as with the adjustable wrench aligned to the major axis. I think I understand what is going on with the two wrenches in alignment but I'm still confused that being at 90° gives the same reading. I thought the distance would be a straight line from the pivot pin inside the handle to the bolt head. But that gives me a result that is inconsistent with the torque readings.

I'm still learning...
