Assuming you have signed in to the other device with your account you should be able to use the Activation troubleshooter on your device to transfer the licence.
Use the option Changed hardware.

I accidentally activated windows 11 on someone else's device using my digital license. Is there any way I can deactivate it on the other device and activate it on my own device?

Greetings!
This is Christine and I'll be happy to assist you. You can deactivate the device that you've accidentally activated using your license by following the steps below:
Please click Start menu and type CMD, choose Run as Admin, and paste the command below then hit enter:
slmgr /upk
Once done, it will be deactivated. Then on your own device, just sign in your Microsoft Account, click Start menu, type Activation then hit enter, click Troubleshoot and I changed hardware on this device recently and choose your device, finally click Activate.
Feel free to ask if you have any question. I'm just here. :)
Thank you :)
