Do they make a device to use to put on keg to keg it from over carbing ?
Yes, it's called a pressure gauge.
Seriously, I never recommend carbing at higher pressure, it just leads to problems. If you are really in a hurry, set it to the proper psi for the temperature and the volumes of CO2 you want, then shake it a lot. It will carb just fine, with no risk of over carbonation.
For your current problem, was the head space the same in the kegs? If the two problem beers had more headspace, when you turned the pressure down there would have been more gas in those kegs which could have kept carbonating the beer.
If you are patient, I would vent the beer, wait, vent, wait, repeat, blah blah blah. Eventually you can just let it sit at serving pressure/temperature for a few days and it will carb up fine.
If you are not patient, do the same as above but shake it every time you vent, it will drive the CO2 out of solution.
Let us know how you choose to fix it.
