Lofting Circles

I've ran into this problem a couple of times and decided to ask for help. The pictures should explain most of it but whenever I loft a circle, the resulting surface twists randomly (I figure it's because the circle plane is twisted or somehow not aligned?). So my question is, if there is some way to create an "ideal surface" from these two curves?

Any help is appreciated!

You need to align the starting point of the circle at the closest point to the starting point of the closed curve.

Here's the example

You can align the sections in the Loft Options, the O-input:

I always forget about lofting options! Life can be so much simpler

Awesome! Thank you both for your efforts. I worked out perfectly (with the loft option)!

Is this also possible for lines?

I have circles arranged in a spiral. I subdivide these circles into points and I would like to connect these points with a Nurbs curve. But whenever I do that, there is a similar problem, and in some places I have nodes where the start and end points are twisted.
