So I am making a system of rotating where your cursor points, the game will rotate the turret to direction that mouse is at.
I know I could do this with CFrame but I would prefer finding the angle that I can apply to a hinge more than CFrame

You can calculate the angle using CFrames as well.
Here is how @ThanksRoBama calculate the yaw angle, or y axis rotation for his turret.
Visualization:
local object_horizontal_offset = yawBase.CFrame:PointToObjectSpace(target.Position)
local object_yaw_angle = math.atan2(-object_horizontal_offset.X, -object_horizontal_offset.Z)
--Yaw angle is the goal CFrame
--Next is PID stuff which I believe you are not concerned with
--yawBase is the base of the turret.
--I heavily suggest experimentation by printing out the values or
--some other value monitoring method to make sure you get the right angle
print(object_yaw_angle)
Edit: Yep here is how it works by measuring the horizontal yaw angle relative to the parts look vector, a reminder that this angle is relative to yawBase CFrame position and orientation.

is there a way to make it follow mouse without having you to click though

Yep, just use a constant loop to make it follow the mouse 3d world position preferable RunService Heartbeat since normally it runs faster and hence more responsive than a while true do wait() loop.

Yeah I’m already running a while loop but I can’t pass mouse position without using Mouse.Hit

Why not use mouse.Hit.Position, what are the problems are you facing?
Edit: There is also Camera | Roblox Creator Documentation to convert 2d cursor position to 3d world space which your turret is located I believe when you mentioned hinge. Is this what you were looking for?

I just don’t want the player have to click to rotate to the direction but rather rotate with their mouse as it moves

Nevermind I’m just stupid and thought Mouse.Hit responded for when mouse was clicked

Is there any way to do the same thing but with Y-axis?
