I wouldn't recommend cranking down on that adjustment screw, just go a little at a time.

As I mentioned previously and as ND pointed out, going crazy on the adjustment can have some very undesirable results, broken thumbs or wrists from the steering wheel getting jerked or having the box lock-up while driving and not being able to steer.

The torque wrench ins't for the adjusting screw... you only adjust the screw a little at a time.

The way to tell when you are adjusting it in too far (this is after minor adjustments 1/8 to 1/4 turns in) is when you are driving straight and you slightly turn and it does not want to return to center, it can go from wandering when loose, to wont return back when tight, at the dealer years ago, it used to be a standard adjustment we made when doing alignments on high mileage vehicles, the road test after the align you took your long screwdriver and a wrench, usually no more than a 1/2 turn, if it still is sloppy but goes tight when turning means the sector shaft is worn, sometimes new bushings help, but if the teeth at the crown (center) of the sector are worn nothing can be done other than replacing it, part store rebuilt boxes that are seals and bushings only no hard parts, will tend to have a little slop and be a little tight when turning, which is also where you can adjust a old box to , BUT, too tight, side loads the sector really bad, dont over adjust it is the main thing.
