What is this Old family RAF token/medal?

[Blakeatron]

Mum has been digging through her old boxes and found this piece from her Grandad - I've been googling but cant find out what this is - it looks like a medal but no clasps, so assume some kind of token?

[magooagain]

The Latin is the Royal Air Force and commonwealth members air forces emblem meaning
Adversity to the stars or something like that.

It may be a sporting medal or it could be a medal given as a member of the Royal Air Force.

[Slushbox]

Very similar to RAF Royal Tournament planchettes from 1924.

'Through difficulty to the stars'
