Torquing the bow means that you're exerting some force on the bow handle other than straight toward the target. It could be a twisting force or a bending force to one side or the other. Target archers eliminate torquing by holding the bow in the V of their bow hand, without their fingers or thumb touching the bow handle, and using a bow sling to catch the bow after the shot. If you try this without using a bow sling, you will grab the bow reflexively as the shot goes off and this will cause as many problems as torquing.
Trad hunters don't usually have time or desire to set up a bow sling, and so have to do the best they can holding the bow in their bow hand. The way I do it is to hold the bow with my thumb and index finger only, with the other fingers simply touching the back of the bow handle. Because the bow handle is pressed against the meaty part of my hand between my life line and the base of my thumb, my knuckles are angled off at approx. a 45 degree angle. Again, just don't hold it so loosely that you have to grab it when it goes off.
