I'm seeking some expertise to verify a quiz question answer at work is it correct that Boeing calls a Ram Air Turbine (RAT) an Air Driven Generator (ADG)?

Also, please can you provide a reference I can quote in order to settle any arguments!

Many thanks for any help.

Boeing calls it a RAT, Airbus calls it a RAT, Bombardier call it an ADG. Relevant system manuals found on smartcockpit.com should settle any ensuing arguments.

AoG is correct. The confusion may have arisen as the 767, in addition to the RAT, has an ADP (Air Driven Pump) from the Centre Pneumatic Duct serving the Centre Hyd system Demand Pump.

Bombardier calls it an ADG on the CL600 derivatives because it is an Air Driven Generator which supplies HYD pressure by the ADG powering the #3B pump rather than having an internal pump in the RAT.
