You said "Any forces which operate between the collection of objects taken as a system are not able to convert angular momentum into linear momentum or vice versa."
One gas with linear momentum can affect the angular momentum of another gas to cool that gas. This is how helium is liquefied. Yes, this refrigeration process takes energy but linear/angular energy interaction is possible.
