It sounds like you have a gooseneck like the Atwood Gooseneck Trailer Coupler AT75401. For an adapter to kingpin, I recommend the Bulldog Gooseneck-to-5th-Wheel Trailer Coupler Adapter - Inner Tube - Square - 30,000 lbs # BD0289650300 or the # KPG5-Q25-IP. Both measure 4 inches outer diameter to fit inside a tube 4-1/2 inches outer diameter.
Another option is to use the Bulldog Gooseneck-to-5th-Wheel Trailer Coupler Adapter - Square - 30,000 lbs # BD0289590300. This will only be needed if your 4-1/2 outer diameter dimension was on the inner tube assembly. Basically this will give you a 3 layer coupler instead of a two layer due to initial outer tube size. This would be rare, but possible.
