Yes, the proper torque is a lot more than most riders would use without a torque wrench and I don't think any one can just hold a properly torqued cassette with their hand while removing the lockring.
My Park and Shimano pinned lockring tools have 1" and 15/16" (24 mm) outside hexes respectively so a matching 1/2" square drive socket can be used on a torque wrench to tighten them.
