Axles point into their local X direction, so...

Take a vector of 1 0 0
Transform it by the axles rotation ( :getRef, :getOri)
Take a vector of abs Y (0 -1 0)
Get the angle between the two by
absYVector:getAngle(absAxleXVector)


Hope this get you on the right path.

ps: I'm assuming you need this for scripting, during editing you better off using the selection information feature.
