Adapter for Pocketdispo lens to my Canon EOS Rebel T3i - what kind of adapter should I get?

I got the Pocketdispo (Canon EOS M Mount) lens for making a music video, but just received it, doesn't fit, and they don't sell a size that fits my camera (Canon EOS Rebel T3i).

Is there an adapter i can get, like a ring adapter? Having trouble figuring out specifications, any recs are helpful!
