Restricting the governor with a overly firm grip is an issue with tense students and low time pilots.
On some older machines the governor stepper motor gets tired and the (non-adjustable) friction clutch wears resulting in a "weak" governor that is easily overridden.
Some examples from the archives below:

The way good (experienced) Robby instructors deal with the death grip, is to instruct the student to place their three back fingers on the collective so that only the thumb and indext fingers are lightly touching the throttle. This way as the student tightens their grip it doesn't override the governor.
I was taught this in 2003 and still do it to this day.
