Can't find an adaptor to attach a flexible 15mm pipe to a threaded 5/8" isolator valve

I'm trying to fit a Grohe tap to a UK isolator valve. I know there's a metric/imperial discrepancy - as I understand it, Grohe is 15mm, UK is 5/8".
My isolator valve has a nice neat thread that my previous tap attached, to via a flexible pipe with what I believe might be called a "flexi tail". It just screwed on.
The conversion adaptor that I've been given to solve this problem will not screw onto the isolator valve. It's designed to work with an existing length of copper pipe and a compression joint. It doesn't actually help me, because I'm not trying to attach to a piece of copper pipe. I'm trying to connect to an isolator valve which is threaded. So what I need is something that has a small threaded end for the Grohe 15mm tail to attach to, and then a screw-on thing at the other end which will attach to the isolator valve. And I can't find any such thing. But surely they must exist??
I attach some photos. The photos show:
- 1. How the previous tap worked. The flexible pipe screws directly onto the isolator valve.
- 2. What I've been given. It doesn't solve my problem.
- 3. The two parts I want to join together, but can't because the dimensions don't match.

- This is how the previous tap worked.
- 2. What I've been given. It doesn't solve my problem.
- These are the parts I have.
- 3. The two parts I want to join together, but can't because the dimensions don't match.
- This is what I want to do.
