Have have a dirt cheap electric drill/screwdriver with a torque ring on it that is very effective at rapid fastening of at leasts Philips style heads to an appropriate toque.
It finds a lot of other uses where a bigger mains powered unit is not worth the hassle
In practice hand tightening anything critical to an appropriate torque is burned in muscle memory for small stuff that isn't that critical anyway.
I am not rebuilding engines these days :-)
