Coupler or Coupling

60103

Pooh Bah
I now confess that with all my years in the hobby, I don't know the difference between coupler and coupling. (well, coupling as the act, but I mean for the metal lump) Is there a difference? Regional? Interchangeable?

It's not rocket surgery
Wouldn't Coupler be a noun, as to what it is; and Coupling a verb, as in what they do with it?

What Triplex said: "Coupling" in the UK is both the noun and the verb. Just like "painting", as in:

"What are you doing with those paints?"
"Painting a painting."

;) :D
