FWIW, you can get torque screwdrivers that will give you the correct torque. Place I used to work in used them for tightening the valve cores (which strictly speaking are also supposed to be torque tightened). A bit picky though, and means every torque screwdriver has to be on the company's calibration register, etc etc.
