Problem fitting extra Tado Valve in a bedroom

I have already fitted a tado control system which all work perfectly well.

I now want to replace a manual Danfloss TVR in a bedroom. But I cannot select a suitable fitting

I have shown a picture of the valve with the Danfloss valve fitted and removed. To me, it looks like the valve is fitted with a Danfloss adaptor. Can anyone confirm this and can I just unscrew it and then fit a Tado valve? I am unsure if I do the radiator will start to leak. Thanks for any advise.
