Mounting outboard

On the subject of tenders, our Zodiac Roll Up came with a manual pump and a twist locker adapter that looks like this...

The adapter doesn't seem to be compatible so I ended up borrowing an electric foot pump and holding the adapter in the valve. Does anyone know if Zodiacs have a special twist lock adapter or do you just use a plain circular one?
 
I just used whatever came with the foot pumps or the electric pumps. They usually have a set of different attachments.
Not always a perfect fit, sometimes you have to hold them so they don’t leak air
