I'm trying to find an adapter that has the 'male' quick release on one side (the one found on the adhesive mounts that come with the Osmo Action) and the standard action cam (plastic fins with a screw through them) on the other side.  
This seems such a simple thing but I'm coming up short, which makes me wonder if there is a term for this that I'm not aware of.

Is there something I am missing?

Hello there CruiseHabit. Good day and thank you for these information you have given. You may try check our DJI Where To Buy platform on this link ( https://www.dji.com/where-to-buy ) to see if the sad mount that you need is available. In addition, I hope that you can get some recommendations from our fellow DJI members who owns the DJI Osmo Action with regards to this inquiry. Thank you and please be safe always.
