The strength of your arm is the applied force on a screwdriver.
The actual force may be the same, but a screwdriver with a large HANDLE can be more effective in applying that force. You can grip it and apply force easier.
It's all about torque. Basically, the further away from the pivot you apply the force, the less force you need to apply. Since the screwdriver means you can apply a force further away from the pivot (where you put the head of the screwdriver underneath the lid of the paint can), it means you can apply less force.
It increases the applied force and changes its distance and direction. -Novanet
A screwdriver allows you to exert more torque on a screw. Torque is defined as the product of the force exerted and the distance from the center of rotation. Torque is essentially a rotational force. It is simple to increase torque, simply increase the distance from the center that the force is being applied, and there is greater torque without increasing your effort. The handle is made to be wide, so that a greater torque can be exerted. It is also much easier to grip a screwdriver than it is to grip a screw. That also plays a factor.
When a screwdriver is inserted into a screw, it creates a mechanical connection that allows the user to apply torque. The shape of the screwdriver's tip matches the screw's head, ensuring a secure fit that enables the turning motion needed to drive the screw into or out of a material. This action converts the rotational force applied by the user into linear force, enabling the screw to penetrate the surface. Proper alignment is crucial for effective use, as misalignment can strip the screw head or damage the material.

Both force and distance increase. You have to use force to turn the screw from point A to point B.
output force is al ways less than input force
No, a screwdriver does not multiply force. It is a tool used to transfer torque and apply force to turn screws and bolts, making it easier to tighten or loosen them.
The input force is applied at the top of the screwdriver handle by the user's hand. The output force is exerted at the tip of the screwdriver where it makes contact with the screw, allowing it to be twisted into the piece of wood.
A screwdriver can damage the slot(s) by deforming the screw-head by either too much force or by using the improper size of screwdriver .
by changing the force
It is difficult to exert a large force using a screwdriver because the handle of a screwdriver is usually short, which limits the amount of leverage you can apply to turn the screw. This makes it harder to generate a significant amount of force to drive the screw into a surface.

It's all about torque. Basically, the further away from the pivot you apply the force, the less force you need to apply. Since the screwdriver means you can apply a force further away from the pivot (where you put the head of the screwdriver underneath the lid of the paint can), it means you can apply less force.
A screwdriver can be considered a wedge because the tip of the screwdriver is tapered to a point, which allows it to push into materials and separate them. The force applied to the handle of the screwdriver is transmitted to the wedge tip, allowing it to exert pressure and make it easier to turn screws.
The work done by the screwdriver on the lid is 3.2 J. The formula for work is Work = Force x Distance. Therefore, rearranging the formula: Work / Distance = Force. Thus, Force = 3.2 J / 0.3 m = 10.67 N.
