A handyman purchased this handle, but it doesn't seem to fit the valve. Am I missing something, or is it simply the wrong handle?

Hi! Here is my previous topic, for reference, but it's probably not necessary to look at.

After a handyman came and replaced the Delta handle/cartridge on the shower, now it does not get fully hot. I am not sure which cartridge exactly he installed.

I've attached a video of the cartridge mechanisms as I try and adjust it myself.

Thank you for any advice!

Hello,
My mother has been trying for weeks to fix heavily dripping water from her shower.

She wants to start by replacing the cartridge, but I am having trouble taking off the handle.

Please check out the video to see, and thank you deeply for your help!
