I have the same torque adapter. I use it with my 3/4 drive extendable handle ratchet. Works great for all sorts of things from axle nuts to large machinery.
It is nice to see a real time measurement of torque. In some ways, it is like a beam torque wrench that doesn’t suffer from parallax error.
I particularly like the peak and tracer functions. For instance, when torquing a castle nut on an axle, and then turning it to the next cotter pin hole, you can see the resulting final torque. Attached photos below shows a VW axle nut brought to torque spec (253 Ft*Lbs, overshot a couple and hit 255), and ended with a final torque of 357 Ft*Lbs after turning the castle nut around to the next cotter pin hole.
